History Of Human Origins In A Nutshell

One of our biggest leaps, as species, was leaving the trees we was swinging around in like little Tarazan ape sons of bitches, because the food ran out. Weren't no more food in the trees. Tasted like shit anyhows. Swinging through trees gave us great 3D perception-vision and the ability to imagine what would come next. (Like Keanue Reeves, "Whoa dude, where's the next branch?") Time came when we had to get our monkey shit out of the trees and head on down to the savanna. Oh hot, dry, savannah!! Who needs all this hair out here? Ain't no need being all hunched up out of the forrest. Yo! Stand up, pick up a tool, yammer to the next monkey dude next to us to see what's up, get some language and symbol making going on. BOOM, humans are here on the geological scene.
